3. An office copier has an initial price of $2,300. A service contract costs $200 for the first year and increases $30 per year thereafter. It can be shown that the total cost of the copier after n years is given by C(n) = 2,300 + 185n+15n. C(n) The average cost per year for n years is given by C(n)= n Complete parts (A) through (C). (A) Find the rational function C. C(n) = (B) Sketch a graph of C for 2 n 20. Choose the correct graph below. OB.
